Abstract
A power transmission unit including: a first prime mover; speed change gear pairs; output members; a differential mechanism, which has a first rotary element connected with the first prime mover, a second rotary element, and a third rotary element selectively outputting the power to the output member, and adapted to perform a differential action among those three rotary elements; and a second prime mover connected with the second rotary element. The speed change gear pair includes at least one pair of first speed change gear pair, arranged between the first rotary element and the output member and allowed to transmit the torque selectively, and at least one pair of second speed change gear pair arranged between the third rotary element and the output member and allowed to transmit the torque selectively. A locking mechanism locks the second prime mover selectively to halt a rotation of the second prime mover.
